-small allows players to play the smaller 9x9 board.
-medium allows players to play a 13x13 board.
-large allows players to play the default 19x19 board.
-size=N allows players to play on an NxN board.

BASIC MOVES

Players take turns claiming cells on the board, at
least one cell per turn. Players are not allowed to pass on their turn.

Define “connection” here as an adjacency between two neighboring cells.
If you claim a cell which has two or more connections with enemy
cells, you must claim at least one more cell while it is still your turn.

Your turn concludes when you claim a cell which does not have two
or more connections with enemy cells.

You are never required to form connections with enemy cells unless the
only cells available to you connect to enemy cells.

OBJECT OF THE GAME

Once all of the cells have been claimed,
the player who has claimed the majority of cells wins.

EXAMPLE PLAY

Here one player will be X and the other O.
In Figure 2a it’s O’s turn. In Figure 2b O has claimed a
cell which has two connections with X cells, so he must claim
another cell while it is still his turn.

In Figure 2c O has claimed another cell which has two
connections with X cells and so he must claim yet another cell
while it is still his turn. In Figure 2d O has claimed a cell which
has no connections with X cells thus concluding O's turn.

Now, continuing the same example, in Figure 3a X has claimed a
cell which has three connections with O cells, and therefore
must claim another cell while it is still his turn. In Figure 3b X
has claimed a cell which has only one connection with an O
cell thus concluding X's turn.
